Abstract
A head up display including an image-light source, at least one reflector and a light modulation device is provided. The image-light source is configured to provide an image light. The at least one reflector is configured to transmit the image light to leave the head up display. On the transmission path of the image light, the light modulation device is disposed in the head up display. An ambient light enters the image-light source after passing through the light modulation device, and a light energy of the ambient light entering the image-light source is less than or equal to 25% of a light energy of the ambient light entering the head up display.
